About WDB

WDB is a database system designed to store meteorological, hydrological and oceanographic (MHO) data in a PostgreSQL database management server. The purpose of the WDB system is to improve the quality and effectiveness of IT systems for MHO production by providing a flexible and effective data storage solution for real-time and archive data. The system:

  • Can decode and store meteorological and oceanographic forecast fields
    • WDB has loading programs to load forecasts, analysis, wave and circulations models stored in GRIB1 and FELT format. Metadata is provided for Norwegian HIRLAM fields and some ECMWF data.
  • Has a flexible retrieval interface
    • The WDB Call Interface (WCI) allows the extraction of entire fields or points (time-series) from the database using an SQL-based function interface.
    • WCI is compatible with C++; it should be usable in C, Java, Perl, Python, Fortran and other programming languages that support data acess to Postgres as well (however, these interfaces are not currently tested).
  • Is Open Source
    • WDB is licensed under GPL2 or (at your option) any later version.
